13 clubs... I feel I've plenty of them to work around the greens, but I feel I'm lacking distance. I firstly thought about adding the 4 iron (I don't think it collides with the 4H hybrid) but then I thought about getting a 3H hybrid (I fell in love with Titleist's 913H hybrid because it can be assembled with an Aldila RIP Phenom shaft which I like a lot). I know they are different clubs but hear the rest ;)

I also think a Cobra AMP Cell Fairway Wood 5-7 could fit...

Summarizing it all we've got:

4 iron (mostly because I already own it so I shouldn't spend extra money to get it);

3H (19 degrees) Titleist 913H Hybrid (because of its shaft and extra yardage than the iron);

The only gap I see in your bag is between 4-wood and driver and that is marginal at best. Adding a 4-iron would be silly considering you already have a 4-rescue. These are interchangeable clubs. Adding a 3-rescue is nearly interchangeable with a 4-wood so I don't like that change either.

I believe your bag would be more complete if you ditch the 4-wood and add a 3 & 5 wood to replace it.

I think sometimes by wanting an extra club at the long end of the bag it can end up changing the whole top end set up completely! But hey! Trying and buying new clubs is all part of the fun! Costly, expensive fun!!

Seems like if there is a gap or duplication of similar clubs it's between driver and 4w and 4h and 5i. The VRS 5i is 24 degrees at 38.75 so pretty much a 4i. If it was me and I hit my 5i consistently I'd look to redo everything between the driver and 5i or rethink the wedges at 48-52-56-60. His pw is basically a 9i at 44 degrees.

If you're using it off the deck, I think the 16.5 4 wood serves your long wood purpose. You'd have to hit a 3 wd on the screws all the time to gain a difference

The 22h is like a 7 wd but may not go as high and is more like a 3i

You seem to know your bag, and it's the 4i slot to where you're looking -- I'd find a 25 hybrid to fill the slot (or something that can be adjusted to fill the slot)

It depends on where you want your distance -- long term you may want to look at a 3wd, 5wd setup if you're looking at off the deck longer distance. Plenty of used clubs, or on sale clubs out there at golf stores where you can talk people down. They certainly are giving customers anything at trade-in.
